In order support the current distribution of sine sinuate at the magnetic resonance frequency which is the radio frequency volume coil

摘要

An annular conductor configured to support the current distribution of a sine wave at a magnetic resonance frequency (20, 22), a radio frequency coil assembly, a radio frequency shield that shields at least one direction of said annular conductor (30, I and a 32, 34). Cylindrical shield portion surrounding the periphery of (i) said annular conductor (30) and the radio frequency shield, one at least one flat shield portion arranged substantially in parallel to the (ii) said annular conductor (32, 34) I include the Tsu. In an embodiment of a magnetic resonance scanner, is arranged magnet generates (B0) the static magnetic field is superimposed on the static magnetic field gradients to gradient system is selected, the radio frequency coil assembly, wherein said annular conductor It is arranged in substantially perpendicular to (B0) static magnetic field.
